WINDOW CONSTRUCTION.

Specification of Letters Patent.

Patented Nov. 8, 1921.

Application filed August 23, 1917. Serial No. 187,764.

T 0 all whom it may concern:

Be it known that we, JULIA HANNAH (Emma and JOHN EDWARD CRooK, subjects of His Majesty the King of the United Kingdom of Great Britain and Ireland, residents of Selwyn street, Remuera, in the city of Auckland, Provincial District of 'Auckland, and Dominion of New Zealand,

married woman and builder, respectively, have invented a new and useful Improvement in Window Construction, of which the following is a specification.

This invention relates to windows, and its special object is to enable the outside surface of windows to be got at with ease and comfort and without risk to the workmen or other persons whose duties consist of cleaning, painting, reglazing or performing any other operation which requires to be done from the outside of the building, often several stories high, in which the window or windows are situated. Further. it also provides means in the case of sliding or liftable windows for the raising and lowering of the sashes. which can also be locked in any desired position.

Now, according to this invention, the sliding or liftable windows are constructed and hung so that they may be swung into the rooms or building while they are still also enabled to be raised and lowered in the usual way. This is enabled to be performed by hinging each sash at one side of the window (preferably the left hand), the hinges employed being of a special construction and having formed 011 their inner ends, runners adapted to he slid upward and downward in vertical guides recessed into the window stile. sides of the window are specially formed, so as to avoid the necessity of employing separate outer stops and parting slips, while the inner stops are hinged to open inward.

When weights are employed they are rovided at the hinged side only of thewinc ow, and operate in the usual manner. The means for raising and lowering and locking the sashes when weights are not used do not in any way interfere with the hinging of the sashes. Said means consist of two screw rods recessed into the stile on the same side of the window as the hinges and extending the full length of the frame. In this case the hinges, of which there are The stiles on both.

preferably two to each sash have formed at their inner ends sockets or bosses screwed internally to work on the screwed rods, the hinges of the upper sash being mounted on the rear rod and the hinges of the lower sash on the front rod.

By means :of a crank handle mounted through the inner facing, and toothed gear ing'between said crank'handle spindle and the screwed rods, either of the latter can be revolved as required to force the hinges carryin r the sash, upward or downward.

Basement windows are hung from the window frame by means of double knuckled hinges secured to the outside of the top and bottom bars of each sash. The sashes swing outward in the ordinary way on thefirst or usual knuckles, and when it is desired to get at the outside of the window, same can be reversed on the second knuckles which are situated about midway of the top and bottom bars, the hinges not being permanently fastened to the bars, between the knuckles.

The invention will be described in detail with reference to the accompanying drawings, in which,

eferring to the combination sliding anu hinged window illustrated in Figs. 1, z and 11,'the stiles 1 thereof are either steppeo as illustrated in Fig. 4 or formed with in cl'ined recesses 6 as in Fig. 7. Both these formations of window stile obviate the use of separate outside stops and partingslips, the outside stops 2 being formed on the Stile as aresult of the plowing, while the stepping and recessing each dispense with the neces' sityv-for using parting slips.

ith stiles formed-as shown in Figs. 2 and 4 the upper sash 2 slides between the opposite steps 3 against the outside stops 2, and the lower sash 3 slides between the opposite stops 4, the inside stops 5 being hinged to the inside facing and closing against "the lower sash.

In one of the stiles, preferably the left hand, are recessed vertical metal guides b one to each'sash and running the full length of the stile 1 (see Fig. 4). These guides e are shaped asshown in Fig. 5 and areadapted to take the runners 7 of thehinges 8 of which there are preferably two to each sash, the hinges of the upper sash working in the rear guide 6. and the hinges of the lower sash int'he front guide 6.

The sashes are weighted at one side only in the usual way, and when the 'insidestops o are opened to the position indicated by dotted 'linesin Fig. 2, they, the sashes, can bepswung on their hinges 8 -into the room "or building .as indicated Fig. 2). The

stops 5 when closed are secured-against the stiles 1 by thumbscrews 8 -or other form of-temporary fastening.

Aswill be seen from the foregoing'owin to thedOrmation of the "hinges and the-'latters engagement in the vertical guicles6,the

sashes can quite readily and eas'ily'be moved up or down, and-opened into the room -or building at any position.

"Whenthe stiles 1 .are "formed with :recesses Was in Fig. 7, the verticahrails o'f the'sash'es are shaped to engage therein, the guides 6 being shaped tolie flush in therecesses while the runners .7 of the hinges are formediso as to work"in"the guides 6.

The means for raising and lowering the sashes illustrated in Figs. 11 to 15 are situated at the same side of the window as the hinges 8. Two screwed rods '9 having top and bottom bearings 9 are recessed into the stile '1, oneopposite each sash. The hinges 8 in this case have formed at their inner ends internally screwed sockets or bosses 15 which engage and work on the rods 9, the hinges of :the upper sash working on the rear rod 9 and the hinges of the lower sash on the front rod 9. On each rod 9 is keyed .a bevel pinion 10 and each pinion 10 has meshing therewith-a bevel gear wheel 11 horizontally mounted. A crank handle spindle 12 mounted on the backof the stile 1 pro jects through the inside facing and carries a crank handle 13 at its outer end.

On the spindle 12+is keyeda gear wheel 14withbevelteeth on both faces, "the spindle 12 being mounted so that the wheel 14 may be made to engage-'ivith either of the 'hori Zontal wheels 11. By pushing the spindle 12 carrying :thewheel 14 inwardthe latter is caused to mesh with the wheel 11 engaging the pinion 10 on the rear rod 9, so that :the crank 'handle can then be revolved in either direction to cause the rear screwed r'od19 "to be rotated as required to move the upper sash 2 upward or downward.

On pulling the spindle 12 outward the wheel 14 is caused *to mesh with the wheel 11 engaging the pinion 10 on the front rod9 and the latter can thenbe turned -in the.di rection necessary to raise or lower the bottom sash 3.

To prevent the wheel 14 fromicoming out of toothed engagement with either of the wheels 11 when raising or lowering a sasha spring pawl16 (Fig. '14) is pivoted inithe inside fac-ing about the spindle 1'2, with its outer end projecting "far enough'to enable it to be pressed down in order that :its rear end may be lifted out of either ofthecircular grooves 17,18, in the spindle'12 when it isdesired to changethe engagement of the.

wheel 14 with eitherot the wheels 11.

When the spindle is pushedinas far as it will go, or is inthepositionforioperating the upper sash, "the inner end of the pawl 16 rests in the 'firstjgroove 17, and prevents any 1 end movement o'fthespindle, and when the latterispulled out to its full extent or is'in the position necessary for operating the lower sash, the second groove 18 is engaged by-th'e inner end ot+the pawl 16.

Supporting bearings 19 to prevent saggingo'f' 'the rods 9 occasioned by the weight of the'sas'hes, are provided, these bearings 19 being fitted and secured in the recesses 20 in which the rods9 are situated, to bear against the bosses of the pinions 10.

In hanging casement windows. double knuckled hinges 21- a're employed, the flatter 'b'ein somewhat like the ordinary T hinge,

but with a knuckle 22 at each end. These hinges (Fig. 9) are secured to the window frame 23 in the usual way, but the fastenings t0 the horizontal bars 2% of the sash are made about midway of the latter and beyond the second or outer knuckle 22.

To enable the window to be opened and shut as an ordinary casement window, a hole is made through the bottom bar at its inner end and a thumbscrew 25 inserted therein from the inside to engage in a screwed portion of the hinge. This locks the window to the hinges 21 so that the outer knuckles are not used, but when it is desired to get at the outside of the window, the thumb-screws 25 are disengaged from the hinge, whereupon the window can be swung or reversed on the outer lmuckles 22 to occupy the position indicated by dotted lines in Fig. 10.

In combination, upper and lower window sashes; a frame wherein said sashes are mounted for vertical movement independent of each other; screw-threaded sash-controlling rods mounted in said frame, one for each sash and extending substantially the entire length of the frame, both of said rods being mounted at the same side of the sash; screw-threaded collars pivotally carried by each sash and engaging the respective sashcontrolling rods each sash being capable of being swung on its pivotal connections with the collars; a beveled gear for each rod geared thereto; a shaft rotata-bly and slidably mounted in said frame; a manually 0perated crank on said shaft; and a double faced beveled gear mounted on said shaft and adapted to mesh with either of said her eled gears and to rotate the gear with which it meshes to move the sash associated therewith.
